Products include all sub-feeds (i.e. publishers, retransmission, and refresh streams are combined)

The values provided in this table are meant to assist our customers in understanding market data capacity requirements. While great care is taken when configuring these measurements NYSE makes no claims, promises, or guarantees about the accuracy or validity of the values presented.

* 1-second peak This
value represents the maximum bit-rate seen during any 1-second
interval over the course of the report, expressed as megabits per
second. Method of calculation: For every packet sent, the number of
megabits transmitted at layer 3 in the 1-second window ending at
that packet (inclusive) is set aside and recorded. The 1-second
peak is the maximum of these stored values over the course of the
report.

** 10-millisecond peak
This value represents the maximum bit-rate seen during any
10-millisecond interval over the period of report, expressed as
megabits per second. Method of calculation: For every packet sent,
the number of megabits transmitted at layer 3 in the 10-millisecond
window ending at that packet (inclusive) is set aside and recorded.
The 10-millisecond peak is the maximum of these stored values over
the period of the report, converted to megabits per second. For
example, if 100 bytes are transmitted in 10 microseconds
then:
100 bytes per 10 ms, which is 800 bits per 10 ms;
There are 100 10 ms intervals in one second;
800,000 bits per 10 milliseconds = 100 x 80,0000 bits per second,
which is 800 Megabits per second

The following figures are bandwidth estimates based on monitoring in the SuperFeed environment and observations of market data capacity reports published by the disseminating exchanges. These estimates assume exactly one copy of market data for each instrument. Note that SuperFeed is an interactive system, so only bandwidth for subscribed symbols will be sent via TCP to the requesting client. Each connecting client will use their own segregated bandwidth. These bandwidth numbers are estimates, and because message rates are not guaranteed by the market data provider(s), actual statistics may vary from these guidelines.

For rough bandwidth estimates based on not consuming the entire feed, generally these characteristics are seen for record data (L1). Note that these figures can change on any given day, as symbol volume is dependent upon broad market trends and unique circumstances of each publicly traded company.
